[Kde-hardware-devel] Solid device action predicates

[Ozan Çağlayan]

Hi,

Where can I find the complete reference of the predicate rules used in
solid device action files? I'm seeing different usages of different
operators in many projects but I can't get the expected results when I
evaluate them using solid-hardware. One such example is the pipe operator:

$ solid-hardware query "foo.bar == 'PropertyX|PropertyY'"
$

looking at it, one can think that | acts like an OR operator between
PropertyX and PropertyY but that doesn't work in that way, so I wonder
what's the aim of that operator.

Thanks,
Ozan
